Three-phase meter for measuring a three-wire or four-wire three-phase network via a direct connection up to a maximum of 80 A. The following values are displayed on a backlit display with up to 7 digits: active energy (Class 1) and reactive energy (Class 2) for import and export, power, currents, voltages (L-L, L-N), frequency, cos phi, power factor, and apparent power, both per phase and in total. Communication can be established via the integrated M-Bus interface or through the infrared interface. The energy meter has 2 fixed configured inputs and outputs. The output can be used either as a pulse output or as an alarm output, with up to 25 alarm values that can be set. The inputs are used for controlling tariffs or for counting external pulses. The resettable intermediate meter allows for measuring individual intervals. Additionally, the meter can record up to 4 tariffs. The meter is calibrated according to MID and approved according to IEC. The installation width is 7 DIN modules.
